what property would x/2=2 be? (answer)

you multiply 2 to LHS and RHS and get: x = 2x2 = 4.

(2sin18)(cos18) (answer)

recall double angle sin(2x) =2sinx cos x, therefore, (2sin18) (cos 18) = sin 36.

You move terms w/ variables to one side and constant term to the other side: sqrt(3) x -x = -6 Factor out x: (sqrt(3)-1) x = 6 divide the (sqrt(3)-1) from both sides: x = 6 / (sqrt(3)-1) multiply sqrt(3)+1 to both numerator and...

Danielle, To echo/amplify Jon's point: you can of course cancel (x-2), but keep in mind there is a conditon for you to be able to do that: x-2 /= 0; or in other words, the cancellation is only valid for x /= 2.
